Definitions

  • the invention relates to a system and a method for practising the shot accuracy and speed of game equipment.
  • the goal is equipped with a device in which signal lights indicate the points in the goal at which the player should aim a shot towards the goal.
  • a device for measuring the exit velocity of the puck produces a laser beam directed along the surface of the ice or (in the case of a practice area without ice) the ground.
  • the laser beam is cut off by a puck or the blade of an ice hockey stick, this starts a measurement action which results in determining the time taken by the player from the moment of passing to the shot hitting the goal.
  • the system also comprises a light control device placed in the goal and comprising signal lights which indicate roughly the target range in the goal which should be hit by the shot of the player, as well as a device for meas- uring the hitting range, based on a camera, for determining the point hit by the puck shot by the player from the shooting area. Furthermore, the system comprises a data processing device for processing the measurement results from the measuring devices, and a display device for displaying measurement results representing the player's actions.
  • the system which is based on a laser beam directed only on the ground has, among other things, the drawback that if the game equipment rises to a sufficiently high level above the ground surface, the game equipment may not be detected at all, whereby the system does not function in the desired way.
  • the aim of the invention is achieved by a novel system and a novel method, because at least one two-dimensional measurement plane is formed by means of at least one target goal and/or at least one monitoring device formed by at least one game monitoring element, placed around the area for shooting practice, and is capable of detecting the game equipment in a two-dimensional area of a given size, comprising all such trajectories of the game equipment, via which the game equipment thrust from the shooting area hits the goal.
  • the game monitoring elements cannot be bypassed in a normal situation without the game equipment passing through a measurement plane formed by a monitoring device at some point of the measurement plane.
  • the measurement of the location and/or velocity of the game equipment on the two-dimen- sional measurement planes formed by the monitoring devices is reliable and accurate, and it can be used for generating measurement data on different game situations in a versatile way, for example, on receiving the game equipment passed, and on shooting immediately after this, as well as on the durations of time taken for these steps in the game.
  • the system and the method enabled by it can be applied to various team games, because it is not limited to measuring the game equipment in a narrow area only, but the measurement by means of monitoring devices formed by a target goal and/or game monitoring elements covers a large area in both the horizontal and the vertical direction. Simpler embodiments of the system may also be used in more limited areas indoors, because in the simplest way, the system may be implemented by means of only one game monitoring element or one target goal and a central processing unit connected to it.
  • Fig. 1 shows an ice hockey shooting practice area equipped with an embodiment of the system according to the invention, seen in a top view;
  • Fig. 2 shows the shooting practice area according to Fig. 1 in a slanted view from behind the shooting practice area;
  • Fig. 3 shows a game monitoring element to be used in the system according to Figs. 1 and 2, in a slanted view from above;
  • Fig. 4 shows a target goal for use in the system according to Figs. 1 and 2, seen in a front view;
  • Fig. 5 shows one goal opening of the target goal of Fig. 4 in a more detailed view
  • Fig. 6 shows another target goal, for use in another embodiment of the system according to the invention, in a front view.
  • the system shown in Figs. 1 to 5 is designed for practising attacking situations in ice hockey, and particularly the receiving of a pass and the speed and accuracy of immediate shooting towards a goal.
  • a corresponding system could also be applied in connection with other games with sticks, or ball games, in which a player of the game receives the game equipment from another player of the same team for the purpose of thrusting the game equip- ment by means of a stick, or other equipment for hitting the game equipment, by throwing or in another way, to a goal or another target defined by a frame, side posts, or other structures with predetermined dimensions.
  • the system is implemented in such a way that the different components of the system can be placed on a game field for the game to be practised, or in another suitable space where it is possible to practice said game.
  • the device shown in Fig. 1 and intended for practising attacking situations in ice hockey comprises at least the following system components: a goal 10, a target goal 1 1 placed in the goal, two or more game monitoring elements 12 to 14, and a central processing unit 15.
  • the game monitoring elements 12 to 14 and the target goal 1 1 are electronic components, each comprising a separate control unit and being, in this case, connected to the central processing unit 15 of the system in a wireless manner.
  • the goal 10 is an ice hockey goal according to the rules of the ice hockey game, having a frame 10a made of metal tubes, the side and rear parts being covered with a goal net 10b.
  • the target goal 1 1 is a so-called “multiple target goal” formed of a sheet fastened to the front part of the frame 10a of the goal 10 so as to cover the goal in other parts except for, in this case, several goal openings 1 1 a to 1 1 e in the target goal.
  • the target goal is provided with the goal openings 1 1 a to 1 1 e in the upper right corner (1 1 a), the upper left corner (1 1 b), the lower right corner (1 1 c), the lower left corner (1 1 d), and at the lower center (1 1 e), as if between the legs of the goaltender, as shown in Figs. 4 and 5.
  • the number of goal openings 1 1 a to 1 1 e may vary in such a target goal; in other words, it may be only one, or in another case it may be greater than in the embodiment shown in Figs. 1 to 5.
  • the goal openings 1 1 a to 1 1 e of the target goal 1 1 are equipped with signal lights 21 at regular intervals, for indicating the goal opening 1 1 a to 1 1 e which the player should try to hit by the game equipment, to the player 22 practising the shooting.
  • the signal lights 21 are LEDs emitting visible light.
  • the target goal 1 1 comprises a control unit and a power source (not shown).
  • the power source may be, for example, batteries, one or more accumulators, or in some cases also mains current.
  • the signal lights 21 placed around the edges of the goal openings 1 1 a to 1 1 e may be configured to operate so that they are lit one by one from the moment when the game equipment 30 passed to the area 23 of shooting practice passes through the first measurement planes 24a and 24b, to the moment when the game equipment 30 passes through the second measurement planes 25a and 25b measuring the game equipment 30 thrust towards the goal.
  • the number of signal lights 21 lit represents the time taken by the player 22 practising shooting, from receiving a pass to succeeding in shooting the game equipment 30 towards the goal 10.
  • the colour of the signal lights 21 may be e.g. white, red, yellow, or green.
  • the signal lights 21 may also change in colour, or each goal opening 1 1 a to 1 1 e may be surrounded by signal lights 21 of three different colours so that the signal lights 21 lit first are green, the ones lit next are yellow, and the ones lit last are red.
  • the colour of the signal lights 21 represents the shooting speed of the player, for example so that green indicates a good result, yellow a satisfactory result, and red a poor result.
  • the target goal of Figs. 4 and 5 also comprises monitoring devices 20 for determining the hitting of the game equipment 30 in the goal openings 1 1 a to 1 1 e of the target goal 1 1 .
  • the operation of the monitoring device 20 is based on optical sensors (20a and 20b) similar to the game monitoring elements 12 to 14.
  • the monitoring device 20 may be used for determining the point hit by the game equipment e.g. so that light emitters 20a and light receivers 20b are provided at the edges of the goal opening, arrayed in two rows perpendicular or (e.g. depending on the shape of the goal opening) inclined to each other.
  • the monitoring device 20 may be used to determine the point hit by the game equipment 30 in a plane parallel with the goal openings 1 1 a to 1 1 e of the target goal 1 1 , because the plurality of sensor pairs of the monitoring device 20, formed by the light emitters 20a and light receivers 20b in different directions, constitute a kind of an "optical coordinate system".
  • those light receivers 20b which generate a voltage that is changed when the game equipment 30 hits a selected goal opening 1 1 a to 1 1 e, determine the point within the goal opening in a two-dimensional measurement plane, at which the game equipment 30 passes through the measurement plane 20c formed by the light emitters 20a and the light receivers 20b.
  • the measurement planes 20c in the goal openings 1 1 a to 1 1 e may also be used for determining the velocity of the game equipment 20 by measuring the duration of the change in the voltage generated by the light receivers 20b, and by comparing this duration with the dimensions of the game equipment 30, to obtain an estimate on the velocity of the game equipment. Therefore, light emitters 20a and light receives 20b of the monitoring device 20 are, in this case, provided in only one plane in the goal openings 1 1 a to 1 1 e of the target goal (in other words, there is no need for two successive measurement planes in the direction of movement of the game equipment, as in the game monitoring elements 12 to 14). This requires, e.g.
  • a high-speed camera 40 may be placed outside the target goal 1 1 , to be used, in addition to the light emitters and the light receivers, for determining the point hit by the game equipment 30, and for imaging the trajectory of the game equipment from the player's stick to the indicated goal opening 1 1 a to 1 1 d of the target goal.
  • the signal lights 21 are controlled and the monitoring devices 20 in the goal openings are operated by a control unit which is placed in a suitable location in the target goal 1 1 and which is a programmable logic, a computer, or another suitable electronic device for processing electronic data.
  • the control unit is configured to select, randomly or e.g. under control by the central processing unit 15, the goal opening 1 1 a to 1 1 e whose signal lights 21 , light emitters 20a and light receivers 20b it controls.
  • the control unit starts to switch on signal lights 21 of the selected goal opening immediately after the game equipment 30 has passed the second measurement planes 25a and 25b formed by the game monitoring elements 12 to 14.
  • control unit for the target goal 1 1 is wirelessly connected to the central processing unit 15 which in this case gives the control unit for the target goal 1 1 a command to start and stop the light control of the target goal 1 1 and the measurement by the monitoring devices 20 in the goal openings 1 1 a to 1 1 e.
  • the command could also be given directly by e.g. the game monitoring elements 12 to 14, but in such a case the control unit for the target goal 1 1 and the control units for the game monitoring elements 12 to 14 should be directly connected to each other.
  • the game monitoring elements 12 to 14 comprise a frame 16 comprising sup- port means 16a and 16b for supporting the frame in a vertical position on the floor or on ice in the shooting practice area LH. Furthermore, the game monitoring elements 12 to 14 include monitoring devices 24 and 25 formed of several light emitters 17 and light receivers 18 on top of each other, and a power source, a control unit, and a radio transmitter for transmitting the measurement results of the game monitoring element to the central processing unit 15 of the system. Furthermore, a signal light 19 may be provided on top of the game monitoring element 12 to 14 to indicate when the light emitters 17 of the light emitting game monitoring element (in the case of Fig.
  • the game monitoring elements 12 and 13 focus the light sufficiently precisely on the light receivers 18 of the game monitoring element used as the light receiver (in the system of Fig. 1 , the game monitoring elements 13 and 14) .
  • the signal light normally functions in such a way that it is lit if the light emitters 17 and light receivers 18 of the game monitoring elements 12 to 14 are not correctly focused on other, and is turned off when the light receivers receive light transmitted by the light emitters as intended. In some embodiment, however, it may also function in the opposite way; that is, the signal light 19 is lit when the light emitters 17 are correctly focused on the light receivers 18.
  • the frame 16 of the game monitoring elements 12 to 14 is, in this case, formed of a hollow cylindrical piece made of plastic, plastic-coated thin metal sheet, glass fibre, wood, composite, or another suitable material and having a tapered upper end.
  • the support means 16a and 16b extend from the lower end of the side wall of the frame outwards, wherein the game monitoring element 12 to 14 may be placed on a flat ice or floor surface so that the tapering upper end of its frame 16 points vertically upwards.
  • a signalling device 16c is provided at the top end of the frame to indicate when the light emitters 17 are focused on the light receivers 18 of the game monitoring element.
  • one or more ice picks, or the like may be provided, to be pressed into the ice upon mounting the game monitoring ele- ment 12 to 14 on the ice.
  • the game monitoring element 12 to 14 remains stationary even if the game equipment 30, passed to the shooting practice area 23 or e.g. bouncing off the goal, hit the game monitoring element 12 to 14.
  • the game monitoring element 12 to 14 may also be equipped with a flexible shield or cushion fixed on the outer surface of its frame 16, for cushioning impacts caused by hits of the game equipment 30, and thereby preventing displace- ment of the game monitoring elements during the shooting practice.
  • the light emitters 17 are LEDs emitting coherent infrared light.
  • the light receivers 18, in turn, are photovoltaic cells which generate a voltage when they are exposed to coherent infrared light generated by a light emitter 17.
  • the control unit of the game monitoring element 12 to 14 is e.g. a programmable logic, a computer, or another suitable electronic device for processing electronic data, configured to operate so that it measures the voltage generated by the light receivers 18 and transmits the measured data to the central processing unit 15 of the system at a measuring frequency securing that the game equipment 30 cannot pass through the measurement planes 24a and 24b, and 25a and 25b, formed by the game monitoring elements, without being detected by the system.
  • each game monitoring element 12 to 14 comprises two vertical rows of several light emitters 1 7 and several light receivers 18 on top of each other.
  • two measurement planes spaced from each other can be formed between each two game monitoring element 12 to 14 placed in the game area, namely the measurement planes 24a and 24b for the monitoring device 24, or the measurement planes 25a and 25b of the monitoring device 25.
  • the measurement planes 24a and 25b or 25a and 25b of the system shown in Figs. 1 and 2 are presented in a view from above in Fig 3 which illustrates the second game monitoring element 13 of the system.
  • two successive measurement planes i.e.
  • the first measurement planes 24a and 24b are formed between the first game monitoring element 12 and the second game monitoring element 13, and two successive measurement planes (i.e. the second measurement planes 25a and 25b) are also formed between the second game monitoring element 13 and the third game monitoring element 14.
  • two successive measurement planes 24a and 25b, or 25a and 25b it is possible to determine the location of the game equipment 30 by means of two points whose distance is known, when a sufficiently high meas- uring frequency is used.
  • the accuracy of the measurement data obtained is quite sufficient for determining the velocity of the game equipment 30 when it passes through the successive measurement planes 24a and 24b, or 25a and 25b, formed by means of the game monitoring elements 12 to 14. In the way shown in Fig.
  • the light emitters 17 are placed at one location in the direction of the circumference of the frame, and the light receivers 18 are at another location at an (adjustable) angle of about 45 ° to 135 ° from said location. Thanks to the adjustability of the angle between the light emitters 17 and the light receivers 18 in the same game monitoring element 12 to 14, the game moni- toring elements may be placed more easily so that the measurement planes 24a and 24b, or 25a and 25b, formed by them constitute different angles to each other. This makes it possible to take measurements in different game situations and in practice sites having different areas, because the shape of the area to be encircled by the game monitoring elements 12 to 14 may vary more freely than in a case where the angle between the light emitters and the light receivers were not adjustable.
  • the game monitoring elements 12 to 14 collect the measurement data (e.g. voltage) formed by the light emitters 17 and the light receivers 18, and transmit it to the central processing unit 15.
  • the central processing unit 15 determines if an object has passed through the monitoring devices 24 or 25, for example, an ice hockey puck used as the game equipment 30 for shooting practice in the case of Figs. 1 to 4.
  • the central processing unit 15 may be programmed to ignore a change in the measurement data if measurement data formed by merely one light receiver 18 deviates from the measurement data formed by an adjacent upper or lower light receiver 18. Such a line of action prevents interference which might otherwise be caused by objects clearly smaller than the game equipment 30, such as mosquitoes or flies, passing through the measurement planes.
  • the number of light receivers 18, whose measurement data should show a change in order to be interpreted as the game equipment may vary in different embodiments. This may depend on e.g. the type of the game equipment, for which the system is intended or set by programming. For example for a soccer ball, the requirement may be a change in a larger number of light receivers than for an ice hockey puck.
  • the same game monitoring element 12 to 14 may be used both as a light emitter and as a light receiver 18, because the same game monitoring element 12 to 14 comprises both light emitters 17 and light receivers 18.
  • the game monitoring element 12 to 14 is used as a light emitter 17, it is placed on the floor or ice of the shooting practice area 23 in such a way that, for forming e.g. the measurement planes 24a and 24b of the monitoring device 24, the light emitters 17 of the first game monitoring element 12 are focused on the second game monitoring element 13 to be placed at the other end of the measurement planes 24a and 24b, the light receivers 18 of the second game monitoring element 13 being oriented towards the first game monitoring element 12 used as the light emitter.
  • the light emitters 17 of the first game monitoring element 12 which are LEDs emitting infrared light, are used as light emitters and are activated by adjusting their directional angle to make the measurement planes 24a and 25b ready for operation. The readiness is confirmed when the signal light 16c on top of the game monitoring element 13 is turned off as a result of the adjustment.
  • the directional angle of the first game monitoring element 12 used as the light emitter is correct with respect to the directional angle of the second game monitoring element 13 used as the light receiver.
